Answer:
D
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
=3x^3+8x^2-7x-4-(2x-6)
=3x^3+8x^2-9x+2
Answer:
An equation of the circle with center (h, k) and radius r:
Step-by-step explanation:
Not sure what you need to find out but,
An equation of the circle with center (h, k) and radius r:
For a perfect square
b² = 4*a*c
Comparing ax² + bx + c = 0 to x² + bx + 16
a = 1, c = 16
<span>b² = 4*a*c
</span>
<span>b² = 4*1*16
</span>
<span>b² = 64
</span>
b = √64
b = 8
The value of b = 8.
